Tutorial Request: Coloured object but grayscale background?

[Yodums]

I've tried going through the tutorials in the sticky but haven't been able to find what I'm looking for. Let's say I take a picture with me and a background. What some people do is keep the background black and white, but keep "me" in colour. How is this done using Photoshop? I also want to keep all original colours of me. There's a tutorial link in the sticky that show how to brush something a certain colour.

i.e.



Credits as stated on the image.

Thanks in advance.

-Choose the object you want to keep colored with the lasso tool.
-Press "Cntrl + Shift + I" to select the inverse.
-Go to Image > Adjust > Desaturate.

Done.

Thanks for such a quick reply. Very helpful and informative post.

No problem, glad I could help.

Are there any further tips you can give? Are you using the magnetic lasso tool, or just the plain tool? I'm trying to colour a rather large object, so it's tiring to keep my mouse button held down for how many seconds. Is there a trick to possibly "resume" the lasso tool after you've let go of the mouse button?

Thanks in advance.

I usually use the polygonal lasso tool and just do multiple clicks. On larger images, I will box it off, meaning do it by sections and not the whole thing at once, and then just use the Shift button plus clicking to add onto the existing selection. hope that helps.

Edit: Remember, lasso'ing can be tedious and time consuming, but the extra time spent will show in the final product. Also, set your 'feather' to 1 px, it comes out smoother.

There are actually a ton of ways to do this. You could use two layers of the same image with a Layer Mask, revealing the color image and hiding the top Grey Scaled image. You could just use the Lasso/Vector tool to outline your selection and copy it to a new layer and Dessaturate it and then just Adjust the Levels/Curves. You could even use the Quick Mask mode to go back and forth with your selection.

There should be a feature (different from a selection brush, which "paints" a selection) which you can use to select color, with varying tolerance levels. I did that on one of my pictures of my car.
